Abstract

Current chat and instant messaging (IM) solutions within the DoD have created problems with information security and interoperability. Though Extensible Message and Presence Protocol (XMPP) is the only mandated chat and IM protocol in the DoD, the majority of the military still operates alternate nonstandard solutions that prevent interoperability and lack appropriate security assurances. XMPP is a streaming XML protocol used for multi-user text chat and Instant Messaging (IM). XMPP supports a large set of administrative and user features, valuable to military chat and IM users. As an open standard, XMPP is also extensible to allow for development of military-specific chat and IM requirements. XMPP protocol also provides significant extensibility to allow for greater command and control and other operational capabilities. This work demonstrates the use of XMPP to route XML-expressed Distributed Interactive Simulation (DIS-XML) data to conduct distributed modeling and simulation. This work also demonstrates the use of XMPP as a generalized XML message-routing framework in conjunction with XML-expressed military data models, such as the Joint Consultation Command and Control Information Exchange Data Model. Also presented in this thesis is an XML document based chat data logger, designed to support persistent operations using distributed chat architecture. Experiments conducted with Navy Exercise Trident Warrior 2006 demonstrate the value of such a framework, as well as the value of XML document-based chat data logging. Results indicate that implementation and extension of XMPP has significant value for enhancing command and control. These features, along with the benefits of the adoption of open standard solutions, make XMPP an essential technology for adoption in todayâ s operational command and control suites.
